It is possible to park on-site before the event starts and Weymouth will then be a hive of activity throughout race day.
There will be plenty for spectators to do around the seaside town for the family, before cheering you around town and watching you finish on the Esplanade.
Kit List
All you really need to finish a triathlon is a swimsuit, bike, bike helmet and running shoes. There's plenty of additional gear for each leg of the sport, and how much you buy depends on your goals and commitment. We recommend starting with high-quality basics and adding piece by piece as you get deeper into your training.

Did the Half Ironman (70.3) in 2019
A really enjoyable race. This was my first 70.3 and the course was beautiful. Super well organised and I had a lot of fun. The only downside was that they shortened the swim for the second year in a row. I don't think it should have been shortened this year. Hopefully they have a backup plan for future years. All in all, an awesome day out.

Excellent organisation from all the guys at Ironman. Especially enjoyed the pizza at the finish line.
Did the Half Ironman (70.3) in 2019
We had a short swim and the cycle was amazing, I realy did love this part as it was a great route. Lots of support on the run with a great atmosphere.
Did the Half Ironman (70.3) in 2019
I'll review this through the 3 events, the swim (00:23) was shortened for the second year in a row which as a terrible swimmer is fine by me but must be incredibly frustrating for the very good swimmers who have to stand around in transition for nearly 3hrs, with the rain, getting cold to do a 15minute swim, the bike (03:03) course was actually good fun, shame about the weather (as it would have slowed peoples avg speed down a bit) but the two hills were a very good test and at no point did i feel bored which can happen on long rides. The run (01:41) was basically flat so wasnt a challenge physically but mentally was very boring as it was just up and down the esplanade so you would see the same thing 6 times. Overall (05:21) though the event was brilliant and I thoroughly enjoyed it.

A long day out, but very enjoyable.
Did the Half Ironman (70.3) in 2018
I could write 1000's of words about this but will try and keep it short- increidble day sums it up- can be a tough swim with soem big waves- fairly fast biek with mostly good roads (the odd track) and 3 climbs, a flat run with some great support and just 1 quiet section on each of the 3 loops
